CP同步、文件系统FS同步以及新CP使用的故障与处理

CP同步、文件系统FS同步以及新CP使用的故障与处理 CP同步、文件系统FS同步以及新CP使用的故障与 处理 交换机运行时，要求有两个CP板卡正常运行，并且处于互为备份备用状态。由于运行时 间较长和使用频繁，往往有的CP板卡出现损坏或是其他的问。使得主备CP板卡处在非同步 状态，文件系统FS也处在非同步状态。此时，必须及时处理，保证交换机正常运行，需要对 CP板卡进行处理或是更换新的CP板卡来替代。 CP及文件系统FS的正常运行状态 > d fs Fs adminState = unlocked operationalState = enabled usageState = active volumeName = GXNNPP15K01 activeDisk = Fs Disk/0 syncStatus = Synchronized syncProgress = 100 % capacity = 4294770688 bytes freeSpace = 2339176448 bytes usage = 45 % ok 2006-04-19 11:22:35.59 > d fs d/* Fs Disk/* +====+-----+----+-----+-----------+----------+-----------+----------+---------- |Disk|osiAd|osiO|osiUs|volumeName | capacity |unformatted|freeSpace |badBlocksP | | min |per | age | | bytes| Capacity | bytes|ercentage | | | | | | | bytes| | % +====+-----+----+-----+-----------+----------+-----------+----------+---------- | 0|unlck|ena |activ|GXNNPP15K01|4294770688| 4294967295|2339176448| 0 | 1|unlck|ena |activ|GXNNPP15K01|4294770688| 4294967295|2339176448| 0 ok 2006-04-19 11:22:38.78 注意:MSS 7K CP板卡处在0和15槽;MSS 15K CP板卡处在0和1槽 如果是新插入的CP板卡，或是CP板卡都正常，并且磁盘都可用，但是同步状态为不同 步，可以使用同步命令进行同步操作: > d fs Fs adminState = unlocked operationalState = enabled usageState = active volumeName = GXNNPP15K01 activeDisk = Fs Disk/0 syncStatus = unSynchronized syncProgress = 0 % capacity = 4294770688 bytes freeSpace = 2339176448 bytes usage = 45 % ok 2006-04-19 11:22:35.59 > d fs d/* Fs Disk/* +====+-----+----+-----+-----------+----------+-----------+----------+---------- |Disk|osiAd|osiO|osiUs|volumeName | capacity |unformatted|freeSpace |badBlocksP | | min |per | age | | bytes| Capacity | bytes|ercentage | | | | | | | bytes| | % +====+-----+----+-----+-----------+----------+-----------+----------+---------- | 0|unlck|ena |activ|GXNNPP15K01|4294770688| 4294967295|2339176448| 0 | 1|unlck|ena |activ|GXNNPP15K01|4294770688| 4294967295|2339176448| 0 ok 2006-04-19 11:22:38.78 同步文件系统的命令为: > synchronize Fs > d fs Fs adminState = unlocked operationalState = enabled usageState = active volumeName = GXNNPP15K01 activeDisk = Fs Disk/0 syncStatus = Synchronizing syncProgress = 1 % 直至同步到100,，syncStatus值为Synchronized capacity = 4294770688 bytes freeSpace = 2339176448 bytes usage = 45 % ok 2006-04-19 11:22:35.59 如果出现不同步的情况，首先要对不能正常工作的CP进行处理，如下: 查看磁盘状态 > disp fs disk/* Fs Disk/* +====+-----+----+-----+-----------+----------+-----------+----------+---------- |Disk|osiAd|osiO|osiUs|volumeName | capacity |unformatted|freeSpace |badBlocksP | | min |per | age | | bytes| Capacity | bytes|ercentage | | | | | | | bytes| | % +====+-----+----+-----+-----------+----------+-----------+----------+---------- | 0|unlck|dis |idle |n/a | n/a| n/a| n/a| n/a | |Component is disabled. | 15|unlck|ena |activ|JXJJPP07K01| 811122688| 4294967295| 517914624| 0 1 component(s) reported errors. command failed 2005-01-04 15:56:01.16 > d -n fs disk/0 Fs Disk/0 adminState = unlocked operationalState = disabled usageState = idle volumeName = ? capacity = ? bytes unformattedCapacity = ? bytes freeSpace = ? bytes badBlocksPercentage = ? % Component is disabled.
